You can inquire about the products you want from the merchants on the Internet. Generally, big merchants have them, and then tell you your situation, and they will tell you the price. If it is zero, they may not tell you the price. If there are many appliances, you can go to the wholesale department. There are wholesale appliances and consumables in big cities. Then you can ask around for all the models you want, then write down your phone number in your notebook and make a reasonable plan when you go back.

Work clothes should also be compared with suppliers first, and then tell each other what you think. You can provide the basic styles and sizes you want. If you can design it yourself, use your own design. Then, if you don't have a design drawing and need the other party to design it, wait for the other party to design a sample, and then you can show it to the housekeeper to see if it can pass. Then you can make a sample, then agree on the materials used, clothing size, dosage, price, and then customize the time limit. But before you decide, of course, it depends on the strength of the business.
